We should remove all shaders from this list that have been finished already, so we can break the list down and move the finished pages into categories, it's no good leaving new finished pages left in the talk page.--Craziestdan 01:01, 24 January 2009 (UTC)

GPU>=2?$phong -this is like the shader fallbacks- will only use phong if the PC in use has more then 1 GPU. It won't let me add a page for this, because of the syntax, but maybe we should make a single page for all material optimisations?? Thoughts? --Craziestdan 01:44, 24 January 2009 (UTC)

That conditional is actually based on the users graphics settings, not number of GPUs (at least in L4D2). I documented what I could find in Material_optimization. --Rectus (talk) 11:31, 4 November 2014 (UTC)
